通过简单的水热方法成功制备了尖晶石 NiFe2O4 纳米粒子修饰的 BiOBr 纳米片。对所合成的不同BOB/NFO质量比组成的磁性可回收BiOBr/NiFe2O4（记为BOB/NFO）复合材料样品的结构进行了充分表征，并通过在可见光下降解罗丹明B（RhB）来详细评估其光催化性能。 BOB/NFO10（10% NFO）复合光催化剂表现出最高的催化效率，在照射30分钟后降解了99.8%的RhB。降解速率常数分别是裸 BiOBr 和 NiFe2O4 的 1.72 倍和 60.3 倍，这应归因于 BOB 和 NFO 之间异质结构的有效电荷分离和转移。自由基捕获实验表明h+和•O2−在光催化系统中发挥着至关重要的作用。
The BiOBr nanosheets decorated by spinel NiFe2O4nanoparticles were successfully prepared by a simple hydrothermal approach. The structure of as-synthesized magnetically recyclable BiOBr/NiFe2O4(denoted as BOB/NFO) composite samples consisting of different BOB/NFO mass ratios was fully characterized and the photocatalytic performance was also detailedly evaluated through degrading rhodamine B (RhB) under visible light. BOB/NFO10 (10% NFO) composite photocatalyst represented the highest catalytic efficiency, degrading 99.8% of RhB after 30 min of irradiation. The rate constant of degradation was almost 1.72 and 60.3 times as high as those of the bare BiOBr and NiFe2O4, respectively, which should be ascribed to the efficient charge separation and transfer originating from heterostructure between BOB and NFO. Radical trapping experiments showed that h+and •O2−played a crucial role in the photocatalytic system.
